VAM-HVE/HVLT Series
POINT
Sample system
1. When zone interlock is set to “Yes”, priority
is given to energy-saving interlocked control
with commercial multi air conditioners (building
multi). Therefore, individual start/stop of Heat
Reclaim Ventilator Unit cannot be performed
with the central remote controller or Unified ON/
OFF controller.
If there are no commercial multi air conditioners
(building multi) to be interlocked within the
zone, set the zone interlock to “No”. (
③
and
④
on the right)
2. When zone interlock is set to “No”, priority is
given to independent start/stop of Heat Reclaim
Ventilator Unit. Accordingly, energy-saving
interlocked control is not performed.
3. Generally, do not set the precooling/preheating
operation when independent ventilation
operation is started/stopped with a centralized
control equipment. If the precooling/preheating
operation is set, the unit will start operating
after the set time has elapsed.

Function Descriptions
Notes) 1. All the system configurations in this
section use commercial multi air
conditioners (building multi) as an
example. The same controls can be
performed when the air conditioners
are replaced with the SkyAir series.
2.
The system configurations in this
section use wired remote controllers
as an example. The same applies
to the cases using wireless remote
controllers.

Field Settings of “Centralized Zone Interlock Setting” Using Remote Controller
When Heat Reclaim Ventilator Unit is connected to the centralized transmission line (between (F1) and (F2) terminals),
it is necessary to consider changing the default field setting of “centralized zone interlock setting” using the remote
controller.

About
①
Basically, the operations and displays that
are performed using remote controller for air
conditioner can be carried out with the central
remote controller. However, it is not possible
to carry out independent ventilation operation,
ventilation mode switching and air volume
switching using the central remote controller.
About
②
It interlocks with indoor units within the same
zone. Independent ventilation operation mode can
be set on the central remote controller.
Independent operation cannot be performed using
the Unified ON/OFF controller.
About
⑤
When a central remote controller is used and zone
control of multiple units is not performed, one unit
becomes one zone.
To change ventilation rate, etc. other than the field
settings, connect the remote controller to Heat
Reclaim Ventilator Unit.
